Questions and Answers
  • 1. 

    When first powered on, the first instructions a computer will execute are stored in:

    • A.

      RAM

    • B.

      ROM

    • C.

      BOOT Drives Directory

    • D.

      None of these

    Correct Answer
    A. RAM
    Explanation
    When a computer is first powered on, the first instructions it executes are stored in RAM (Random Access Memory). RAM is a type of computer memory that is volatile, meaning it loses its data when the power is turned off. It is used to store data and instructions that are actively being used by the computer's processor. ROM (Read-Only Memory) is another type of computer memory, but it contains permanent instructions that are not changed or erased. BOOT Drives Directory and None of these are not correct options for the first instructions executed by a computer.
